Method

Make sure that your mug is only half full so that the cake has some space to rise and be fluffy.

Microwave it for 1 minute on the highest power.

Note: The timing may vary according to your microwave setting and your mug too. So insert a knife or toothpick after 1 minute and if it comes out clean your one minute cake is ready, if not then microwave to 30 more seconds. And that's about it, you are done. Now, I know we feel like eating our cakes at that very moment, but wait for a few minutes, just a few and dig into it while it is warm.
